- SPOKE-TENONING AND FI ILLY-BORING MACHIN E.

SPECIFICATION forming part of Letters Patent No. 240,014, dated April12, 1881.

i Application filed January 26, 1881. (ModeL) To all whom it mayconcern:

Be it known that I, STEPHEN M. EsrEs, of Clinton, in the county of Rockand State of Wisconsin, have invented a new and valuable Improvement inSpoke-Tenoning and Felly- Boring Machines; and I do hereby declare thatthe following is a full, clear, and exact description of theconstruction and operation of the same, reference being had to theannexed drawings, making a part of this specification, and to theletters and figures of reference marked thereon.

Figure 1 of the drawings is a side view. Fig. 2 is an end view. Fig. 3is a plan view.

This invention relates to devices for boring, tenoning spokes, &c.

The invention consists in the construction hereinafter described, andparticularly pointed out in the claims.

In the drawings hereto annexed, A is a bench supported upon legs a, andhaving the longitudinal slot B.near one end.

0 is a post, whose tenon b projects down through slotB and isheld by thenut 0. Through tenon b is a slot or screw-threaded hole, throughwhich'passes the screw-rod D, having handled, by means of which post Ocan be moved along the bench A..' Post 0 is slotted transversely at c,forming arms E EE J ournaled in this slot 0 are the gear-wheels F G H,the shaft f of the firsthavin g the cranked handle f foroperation.

Passing, through holes 9 g in arms E E and hub h of wheel H is a shaft,I,- carrying a chuck, K, with set-screw It at one end and abalancewheel, L, at the other end, towardcranked handlef. A slot orgroove, 6, on shaft Iengages a pin, h, on the inside of hub h, so thatsaid shaft will turn with the wheel H, but can he slid lengthwiseindependent of the wheel.

Extending to one side from the base of post O is an arm, M, having atits end an upright post,

N, extending above at n and below at n.

Attached to arm M, near to bench A, is another post, P, having at ornear its bottom the pair of slots 1010. Passing through these slots aretread les Q Q, pivoted to the lower end of post N, and connected by rodsq q with the arms rr of the triple lever B, which is pivoted to theupper part of post P. The third arm, 1*, of this lever is connected to arigid rod, S, made fast to a lever, T, which is pivoted to the upper endof post N, and whose other and forked end, t, straddles a groove, o, inshaft I.

Lengthwise of bench A, upon the end away from slot B, and upon the sideof post 0 to which the chuck end of shaft I projects, is a table, U,hung to said bench by transverse swinging staples or loops u 10, havingtheir ends a to extending into holes in the sides of the bench and theirbodies a a passed through loops 8 s, by which they are held in grooves tt at the ends of said table. This table has on top the longitudinalgrooves r r.

Projecting through a central enlarged slot in the table U is a rod, V,made fast to bench A, and havinga nut, M, at its top.

W is a platform, having ribs w w on its under side, lengthwise, and ahole, w, near its center. This platform is placed on table U, the

ribs to w resting in grooves r r and the rod V passing through hole to.

X is a lifting-screw, having the handle 00, and projects through a hole,D in the bottom of bench A, and comes up under table U.

Made fast to the side of post P away from post 0 is a slotted gage,Y,held tight by a binding-screw, Z, passing through slotyinto post P.

This device can be used for boring, drilling, or cutting of any kindbyputting the shank of the implement into chuck K and making it fast nuta 8 5 By the lifting-screw X the table U is lifted up and the platform Wrises,the ribs to w slidin g in grooves r W, and rod V keeping the saidplatform from horizontal motion until the work is at the proper heightfor the tool.

A shaft carrying a chuck and supported in bearings in such a manner thatthe same may be advanced and retracted by a hand-lever is not new, andsuch a construction is not claimed herein.

A tenoning-tool is made fast in the chuck K, and the gage Y is set toallow the swinging leverT, and consequently the shaftI, theproper playfor the determined length of stroke. The

post 0, with its various devices, is set up to the 100 work by the rodD. Power is applied to the crank f of shaft f, and through thegear-wheels is transmitted to shaft 1, which causes the tool to turn. Asit cuts, the shaft is forced inward by pressing on the treadle Q, whichpulls lever T and shaft I toward the work. After finishing the tool isWithdrawn by pressing on the other treadle, Q.

Other classes of work can be placed on the platform W and held in anyproper manner to be operated on.

In operating on spokes it may be advisable to place a support under themon top of platform W. Z is a T-gage designed to guide the spoke whiledriving to the required dish of wheel.

What I claimis- 1. Shaft f, having crank f, wheels F G H, the latterhaving a pin, 71/, on the inside, in combination with shaft I, havinggrooves 41 and o, forked lever T, and treadles for operating the same,substantially as described.

2. In a tenoning and boring machine, the combination of the adjustablepost G, carrying the arm M, having slotted post P and post N,

the pivoted treadles Q Q, rods qq,triple lever B, and pivoted forkedlever T, with the grooved shaft 1. i7 and gearing F G H, substantiallyas and for the purposes set forth.

3. In a tenoning and boring machine, the combination, with the bench A,of the swingin gtableU,having central opening and grooves, r 7 connectedby loops u u to the bench A, with the platform W, having ribs 20 w onits under side, lengthwise, and a hole, 20, near its center, and the rodV and lifting-screw X, substantially as and for the purposes set forth.

4. Table U, held to bench A by swinging loops, and provided with grooveson top, in combination with platform W, having ribs to w on its underside, and a lifting-screw, sub stantially as described.

In testimony that I claim the above I have hereunto subscribed my namein the presence of two witnesses.

STEPHEN M. ESTES.
